Q: Passage: 'The Berlin Wall (German: Berliner Mauer, pronounced (bɛʁˈliːnɐ ˈmaʊ̯ɐ) (listen)) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall cut off (by land) West Berlin from virtually all of surrounding East Germany and East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and finished in 1992. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the 'death strip') that contained anti-vehicle trenches, 'fakir beds' and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the 'will of the people' in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period.'. Question: 'when did the berlin wall go up and down'.
A: 
True
